Hey Janek!

Very astute observation about the ELF format.

Also you inspired me to try the quicksort without boundary checks, code here.

https://github.com/ambeckley/ComparingCandRustQuicksort/blob/main/libunsafe.rs

I think it possibly performs a little bit better than the previous Rust code, but it still has the around same difference to the C code as using the safe.

Let me know if I missed something.

Thanks,

Aaron
